I recently switched to CoreELEC on my Odroid C2., thank you to the developers and the community! Unfortunately the latest update to the 9.0.2 addon repository introduced a problem for me.
The latest mpd (repo 9.0.2, addon 9.0.107, mpd 0.21.4) enforces ALSA output buffering.
It used to work with the following output configuration:
audio_output {
type "alsa"
name "PCM5102 DAC"
device "hw:0,0"
format "44100:16:2" # Required for Odroid!
mixer_type "software"
auto_channels "no" # Required for Odroid!
auto_format "no" # Required for Odroid!
buffer_time "0" # Required for Odroid!
}
With the latest version mpd exits with an error because of the zero buffer time.
With small values I hear strange noise.
With the default value of 500000 the command ‘mpc play’ gives the error: Error opening ALSA device “hw:0,0”; snd_pcm_hw_params_set_buffer_time_near() failed: Invalid argument
Playing a wav-file with ‘aplay -D hw:0,0 -t wav test.wav’ works perfectly.
Is there a way to downgrade mpd to the previous version?
Or is there another solution?
Hi,
Same issue with latest mpd. I downgraded to 0.20.21 version. Hapilly was in ~/.kodi/addons/packages - service.multimedia.mpd-9.0.106.zip. Try update from zip.
The old zip was still there indeed.
Unfortunately I read your message too late and made my own zip…
At least now I know how to build CoreELEC myself
Tonight I fixed the problem by recompiling the previous version of MPD, following instructions from https://libreelec.wiki/compile
On my linux laptop:
sudo apt install gcc make git unzip wget xz-utils
git clone https://github.com/CoreELEC/CoreELEC
cd CoreELEC/
# Need to build libcrypt first manually because (I think) mpd is missing a dependency
# Need to add CCACHE_DISABLE=1 to prevent another error message (found this workaround in https://github.com/ocaml/opam/issues/3395 )
PROJECT=Amlogic DEVICE=S905 ARCH=arm CCACHE_DISABLE=1 scripts/build libgcrypt
PROJECT=Amlogic DEVICE=S905 ARCH=arm CCACHE_DISABLE=1 scripts/create_addon mpd
Be patient, it takes a while…
Now revert to the previous mpd version by replacing some lines in packages/addons/service/mpd/package.mk:
Ok. More complicated but effective. Once I made self compiled addon in Libreelec that I need for music and know it’s quit problematic.
Uncheck automatic updates of mpd addon to prevent from future problems
Does anybody has still those older mpd daemon zips and could give me access to it? I have the same problem and it would allow me to avoid recompilation. Thanks!
I’m quite new to Khadas Kodi. One day I found MPD added on to Kodi sounds pretty good, but there was a problem. That is, when it comes to DSD files I heard constant sizzle noise. I concluded that I ran into the issue specific to ARM MPD 0.21.4. So I also want to get rid of ARM MPD 0.21.4, though I don’t encounter ALSA buffering issue yet.
Thanks to you guys I could manage to build 0.20.21.
I worked on my CentOS 8 box and here is what I did.
Groupinstall ‘Develpment Tools’ and then install the followings;
sudo dnf --enablerepo=powertools install texinfo perl-Parse-Yapp gperf rpcgen golang
